aparcstats2table segmentation fault error
by Eric Yin 15 Nov '22

15 Nov '22

External Email - Use Caution Hello! I’m trying to run the aparcstats2table function on a single participant and I cannot seem to get rid of the following segmentation fault error. I checked the forums and did not find anyone with the same problem. [cid:image002.png@01D8F92C.C6B09C50] I have tried a few different options. First, I read that aparcstats2table requires PATH to lead to python2, but this call would throw the error that freesurfer has not been sourced properly even though I sourced it manually. Please find my Freesurfer version in the screenshot as well. I’m running on CentOS Linux v7 (Core). [cid:image006.png@01D8F92C.C6B09C50] Then I thought that it might be because freesurfer/7.2.0 requires a newer version of python, but it also did not work for python3 or python3.6. [cid:image009.png@01D8F92C.C6B09C50] Please let me know if I’m doing something wrong, or if anyone has run into a similar issue. Thank you for your time.

freeview -v file stuck loading at 99% in 7.2 but not 6.0.1
by Drucker, Daniel 15 Nov '22

15 Nov '22

Hi, If I do: $ freeview -v myfile.nii.gz If I'm pointed at my 6.0.1 freesurfer, this works fine. In 7.2, the freeview window pops up, the loading bar gets to 99%, then then nothing else happens. I'm not sure what to do to debug this further. -- Daniel M. Drucker, Ph.D. Director of IT McLean Hospital Imaging Center Harvard Medical School

Pial surfaces include cerebellum - unable to fix with manual edits
by Raij, Tommi A. 15 Nov '22

15 Nov '22

Dear Surfers, I have a case where recon-all labels cerebellum as cerebral white matter (aparc+aseg.mgz) and the pial surfaces therefore include the cerebellum. The error has been resistant to attempts to fix the situation with manual edits to $SUBJECT/mri/brain.finalsurfs.mgz and re-running autorecon3 (with or without autorecon2). Specifically: Without manual edits, recon-all hangs at the stage: ... CORRECTING DEFECT 0 (vertices=34440, convex hull=821, v0=4192) XL defect detected... ... After exiting with Ctrl-C, brain.finalsurfs.mgz include cerebellum, and the pial surfaces include cerebellum. I guess the "defect" FS is trying to correct is the cerebellum that was mislabeled. My manual edits to brain.finalsurfs.mgz consisted of removing cerebellum by painting with brush value = 1 (freeview voxel edit tool). Thereafter, I recomputed autorecon 3: recon-all -autorecon3 -s $SUBJECT -no-isrunning With this, recon-all finishes "without error" but the recomputed aparc+aseg.mgz still thinks cerebellum is cerebral white matter and the pial surfaces again include cerebellum. This is with Martinos Center stable version 6. Any suggestions would be greatly appreciated! Also happy to send a link to the original T1 and recon-all results if you would like.

How to set original orientation for converted images
by Haiyun Chen 11 Nov '22

11 Nov '22

External Email - Use Caution Hello FreeSurfer Experts, I converted the aseg.mgz file to aseg.nii using mri_convert command, the aseg.mgz file is located in the directory below based on your tutorial: tutorial_data_20190918_1558/practice_with_data/Subj001/mri When I open the file aseg.nii in a different application, the original orientation is not sagittal. In the MRI protocol, the original orientation is sagittal. Could you please help to tell how to set the original orientation of output images to be sagittal? Thank you in advance! Best regards Haiyun
